The Vietnamese CDMA operator, EVN Telecom, will team up with Sky Link, the world’s second largest CDMA 450MHz operator in Russia, to provide roaming service for their subscribers.

An official agreement to this effect, which has been signed recently, will allow the two operators’ CDMA 450MHz roaming subscribers to connect with each other while on trips in Russia and Vietnam.

EVN Telecom, one of Vietnam’s five 3G mobile phone service providers, had over 4 million CDMA 450MHz subscribers in 2010.

Meanwhile, Sky Link, the first provider of 3G mobile services in Russia, had about 1.2 million subscribers in the same year./.
